We are here considering two somewhat similar cars, but we can't deny some of the obvious differences. For a start, they are not even classified under the same segment, with the Opel being a large family car and the Renault representing luxury car vehicle class. The first one has a FIAT-engineered powertrain under the hood, a 4-cylinder, 8-valves 100hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 173hp engine designed by Renault.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the Renault being a slightly better choice apparently. Moving further on, let's take a closer look at some additional safety-related facts. The second vehicle is a luxury car and that gives it a marginal advantage over the large family car competitor, at least that's what statistics show. Furthermore, taking kerb weight as an important factor into account, the French car offers a marginal difference of 8% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Renault does have a slight advantage, when all the models are taken into account. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the Renault badge with 4.1 out of 5. Some independent research have also placed Signum as average reliability-wise, and Vel Satis is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 4.5, while the one under the competitor's bonnet gets 4.8 out of 5.

Renault is way more agile, reaching 100km/h in 4.5 seconds less than its competitor. In addition to that it accelerates all the way to 211 kilometers per hour, 31km/h more than the other car. When it comes to fuel economy the winner has to be the German car, averaging around 5.9 liters of fuel per 100 kilometers (48 mpg), in combined cycle. We can't ignore that 24% difference compared to the French car.

Renault appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, the French car beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Renault outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... I believe that, when we take all into account, we have only one winner here - the Renault. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
